Geeking!

posted by [personal profile] purplecthulhu at 02:59pm on 01/12/2004
As some of you may know, I have a dual 2.5 GHz G5 powermac at work. But I don't think I've run any tasks yet that have really hammered it, or even managed to get the processors hot enough for it to speed up the fans. This is at least partly because I've not been doing much processor intensive work for the last few months.

But now that has all changed!

And I have now managed to hear the fans on the G5!

They're still very quiet, and are almost drowned out by the old Sun Ultra10 I have in my office, but they are audible. Just...

Yay for liquid cooling!

I now return you to less geeky postings!
Mood:: 'geeky' geeky
Music:: The fans! All of them!

How's your G5 compare to my X5DA8, dual 2.66GHz Socket 604 Xeon processors with Hyperthreading (ie. effectively yielding four P4 processors), sharing 4Gbyte ram?

[livejournal.com profile] therealjae will have something to say about the 'my processor is bigger than your processor' geek thing.

I suspect the fans are quieter, but as for speed its going to be dependent on the application, compiler and maybe the data.

You do have more memory than me though, but is the Xeon 64-bit?

This is getting rather geeky, its true!

Define 32bit.

The FSB is 64bit @ 533MHz, the address bus is 36bits (7505 only capable of addressing 16G), each core has the SSE and SSE2 extensions (128bit registers capable of doing math operations 2 / clock), and each core has a MMU.

The program counter (IP) and stack frame(SP,BP) are still 32bit, but if you need 4G of code or 4G of stack (per process), then maybe something is wrong. I suppose, as you say, it depends what your application is.

The X5DA8 has two channels of Ultra320 SCSI, 100MHz and 133MHz 64bit PCI-X slots(in which I have a 3Ware 7506-8 IDE raid 0/1/5/10 controller attached to a five 200G baracudas in a raid 5 configuration), gigabit LAN, and 8X AGP (in which I have a Radeon 9700 AIW).

I have no complaints.
Well, I do have 15 fans (all total) in the case.
